Kerr et al[12]	32-year-old male	Marathon	None	Lateral fracture of the femoral neck with varus displacement and a neck-shaft angle of 90°	DHS + 6 months of partial weightbearing	Full weightbearing, lights sports at 8 months
Scott et al[15]	50-year-old male marathon runner	Increased his running mileage	None	Slightly displaced fracture through the base of the neck of the right proximal femur	3x CHS + 6 weeks of partial weightbearing	Full weightbearing, light sports at 12 weeks
